Wordmark & the 9.
The wordmark is set in JetBrains Mono, heavy weight. sys sits at full strength; the 9 steps back in muted gray. The standalone 9 is the compact mark.
Monochrome only.
Every color is a pure gray — HSL hue 0, saturation 0%. The whole system is built from lightness alone. No accent hue except a single red reserved for error states.

Do
Write the name as sys9, lowercase, one word. Use the bare CLI names (db9, run9) for the tools. Keep generous dark space around the mark.
Don't
Don't capitalize as “Sys9” or “SYS9”, don't add color or gradients, don't put the mark on busy or light backgrounds, and don't stretch or recolor the 9.
